I have a DN power 450mah battery that I need to have the chage/blance lead changed to what my charger takes. The DN power has 4 wires going to it, ones I need only have three going to them, it has a lead that looks like this.

but I need the balance/charge lead that looks like the ones on Ace Power or Great planes. that looks like this

OK, There has to be a adapter out there some place, I am just not sure what I am looking for. Do I need to take better pics so you all know what I am looking for? Sorry I dont know the names of the different charge/balance taps, The DN power has 4 wires and the tap has a little clip on it, the others I have, such as great planes and Acepower battiers have the 3 wires and have two little "guides" or ridges on the taps.

And does anyone know of a place that is USA based? so I dont have to wait 14 days for my product to arrive from china.

No. That appears to be a polarity reversal adapter for a three conductor (2S) JST-XH plug. From your photo, it appears as though you need either a Hyperion or Thunder Power to JST-XH adapter. Recommend that you contact the merchant where you purchased your battery to confirm.
